Gate and data lines crossing each other, a thin film transistor for a switching element, and a pixel electrode for producing an electric field are formed on the lower substrate. The liquid crystal display device operates by using an optical anisotropy and a polarization property of liquid crystal molecules. The liquid crystal molecules have a molecular arrangement direction, and thus the direction is controlled by supplying an electric field to the liquid crystal molecules. That is, the arrangement direction of the liquid crystal molecules is changed by supplying an electric field to the liquid crystal molecules with by switching the thin film transistor, and thus a transmittance of the light is controlled. The light passing through the liquid crystal molecules passes through the color filter, and thus the liquid crystal display device displays images.
- The liquid crystal display device is a non-emissive type display device using a light source. For example, a cold cathode fluorescent lamp (CCFL) is used as a light source, and the lamp is driven by an inverter. The CCFL of the liquid crystal display device can be driven with an alternating current (AC) voltage of approximately 840V.
- As shown in
FIG. 1 , the driving circuit forinverter 100 is partitioned into a rectification/smoothing unit, a direct current/direct current converter (DC/DC converter), and a direct current/alternating current inverter (DC/AC inverter). When anAC 220V is inputted, the rectification/smoothing unit with abridge rectifier 110 rectifies and smoothes theAC 220V to generate aDC 311V. When a power factor correction (PFC) function by a power saving circuit (not shown) is used in order to improve a power efficiency, theAC 220V may be rectified and smoothed to be aDC 400V. Accordingly, theAC 220V inputted to the rectification/smoothing unit may be rectified and smoothed to theDC DC AC 840V for driving alamp 140 through the DC/AC inverter with atransformer 130, thereby driving thelamp 140. Thetransformer 130 is generally a magnetic transformer. - A ground of the driving circuit for
inverter 100 is divided into a hot ground and a cold ground by theSMPS transformer 120. In general, the cold ground may be referred to as an earth. The hot ground is a ground for the DC voltage rectified and smoothed from the AC voltage, and may inflict a bodily injury on a person. A voltage difference between the hot ground and the cold ground may be about 100V. - The driving circuit for inverter according to the related art has two transformation stages through the two
transformers - A driving circuit for inverter with low power consumption is described.
- A driving circuit for inverter includes a rectification/smoothing unit rectifying cating and smoothing a input AC voltage to generate a DC voltage; and a DC/AC inverter inverting the DC voltage from the rectification/smoothing unit to a second AC voltage higher than the first AC voltage.
-
FIG. 1 is a view illustrating a driving circuit for inverter according to the related art; -
FIG. 2 is a view illustrating a driving circuit for inverter according to an embodiment. - Exemplary embodiments may be better understood with reference to the drawings, but these embodiments are not intended to be of a limiting nature.
- As shown in
FIG. 2 , the driving circuit forinverter 200 is partitioned into a rectification/smoothing unit 260 and a DC/AC inverter 250. The rectification/smoothing unit 260 has abridge rectifier 210 using a diode, and the DC/AC inverter 250 has atransformer 230. When anAC 220V is input, the rectification/smoothing unit rectifies and smoothes theAC 220V using capacitor 212 to generate a DC 311 V. When a power factor correction (PFC) function by a power saving circuit (not shown) is used in order to improve a power efficiency, theAC 220V may be rectified and smoothed to be aDC 400V. Accordingly, theAC 220V input to the rectification/smoothing unit 260 may be rectified and smoothed to theDC AC inverter 250. As a result, the DC 311V or 400V is changed to an AC 840V for driving alamp 240 through the DC/AC inverter 250, thereby driving thelamp 240. - The description is based on the use of an approximately 220 VAC input voltage as may found in power systems in countries other than the United States, however it will be understood by those skilled in the art that an input voltage of approximately 115 VAC may used as the basis of the design. In such a circumstance, the voltage at the output of the rectification/
smoothing unit 260 would be reduced proportionately to the input voltage reduction, and the voltage increase in the DC/AC inverter increased accordingly to achieve the required output voltage. - A ground of the driving circuit for
inverter 200 is divided into a hot ground and a cold ground by thetransformer 230 of the DC/AC inverter. The cold ground may be referred to as an earth. The hot ground is a ground for the rectified DC voltage rectified and smoothed from the AC voltage, and may inflict a bodily injury on a person. A voltage difference between the hot ground and the cold ground may be about 100V. The voltage difference between the hot ground and the cold ground should be reduced to drive the driving circuit for inverter 200 smoothly. To do this, the hot ground and the cold ground may be coupled by using acapacitor 214 and aresistor 216. As a result, the driving circuit for inverter according to the embodiment of the present invention may be driven with one stage, and thus power consumption is reduced. - Further, the
transformer 230, according to the embodiment, is a piezoelectric transformer, which has a higher efficiency and less loss than a magnetic transformer. Accordingly, an input voltage of the DC/AC inverter is increased, and the efficiency is improved. A voltage of more than approximatelyAC 840V is required in order to drive thelamp 240. Since theDC piezoelectric transformer 230 may be utilized without a booster transformer. Accordingly, thelamp 240 of the driving circuit for inverter according to the embodiment is driven through the rectification/smoothing unit having an efficiency of 95% and the DC/AC inverter having an efficiency of 85%, by using thepiezoelectric transformer 230. Thus, the efficiency is improved by about 15%. - It will be apparent to those skilled in the art that various modifications and variations may be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
